For this purpose I 38 for the front of the unit.

The in- I provide L shaped brackets I8--I8 which are ner groove being positioned for the reception of suitably secured to header' I4 and these brackets the belt 29 which operatively connects sheave 55 21 to pump sheave 30, the other three grooves being suitable for the reception of three V belts 40 which are operatively connected to a driving sheave on the engine or an electric motor. I provide means for tightening the driving belt 29 in the following manner:

As illustrated in Figure l belts 40 are turned in the direction indicated by arrow. Thus the bottom belt will be the loose one. I position idler sheave 4| on a bearing bracket 42, this bracket being provided with slotted openings on both sides of the bearing and end members I2 are provided with a number of suitable openings 43 for the reception of bolts 44 for securing the bracket to its adjusted position. Thus the bracket may be raised or lowered for the purpose of tightening or loosening the belts. Both members I2 are provided withl openings 43, thus the fan may be u nit.

Pump 28 is provided with a supporting bracket 50 at each side of which are provided slotted openings for the reception of bolts 5|. Member |I is provided with a number of openings for the reception of bolts,5|, thus the pump may be m'oved on its support to a position suitable for the proper adjustment of the driving belt.

which in its entirety is designated by reference character B, comprises tube ends 60-60 and a connecting sleeve 6| which is adaptedto loosely embrace the tube ends and having at each end a stuilng box nut 62, being screw threaded on the ends of the sleeve. The sleeve ends and nuts are adapted to receive packing rings 63--63; thus when it is desired to move pump 28 for adjustmove from header I5 through y the custom in filler caps for radiators.

ing the tautness of belt 29,- one or both nuts may be loosened and again tightened when the pump has been suitably positioned. In Figure 7 the connections between the tube ends are illustrated as being made by means of a. rubber hose 64 having the conventional hose clamps 65-65. The advantage of a rubber hose connection as illustrated in Figure vided a yielding connection between the pump and botton'rnfthe` core unit.

In most installations I provide an overilow tank'61 having gfconnection 68 to header I4 and a filler -cap 69' having a small orifice as is Pump 28 is provided with an outlet tube 52 which is preferably connected to the bottom of the cooling jackets of the engine. I provide a tube 65 which erg-,ends through header I4 and being provided fwith spaced openings 66. 'I'his tube may be connected to the top of the engine jackets from either end; thus the cooling water may pump 28, thence from pump outlet 52 to the engine jacket, thence from the engine jacket into tube 65 as indicated by arrow, whence it is distributed into jacket I4 through openings 66.

'Ihus it will be seen that the pump, fan, wire screens or core A may each be easily removed and replaced; that core A is suspended from its top, the bottom being slidably embraced by end members I2; that the unit is strong and simple, the frame and shields providing adequate protection for the fan and core and that the assembly has a pleasing appearance.

Pump 28 is preferably of the centrifugal'type, the body of the pump being secured to the base by means of a circular gasket and holding bolts, whereby this body may be reversed. Asillusdriven from either side of the` 7-,is that therel will be protrated, outlet 52 is in alignment with an open-,- ing in members I0 and 22 (see Figure 2); thus the body may be turned or reversed whereby outlet 52 points in the opposite direction from that shown, if desired.

Clearly core A may be supported through the bottom header, the top header being slidably held between members I2. In this design however, a cross member between the tops of members I2 would be essential; however in the design shown in Figure 1,-the upper ends of members I 2 are secured together by means of the top header.

Having thus shown and described my invention, I claim.:

1. A device of the class described, comprising side base members, vertically positioned channels secured to the front end of said base members 1 and having their flanges turned inwardly, a radiator core comprising upper and lower headers having tubes therebetween and a multiplicity of ns through which said tubes extend, one of said headers at its ends being secured to said chan# nels, the ends of the other header having brackets which are slidably embraced by said channels, vertically positioned supplemental frame members secured to the rear end of said base members I and a belt forming an operative connection to one of .the grooves of said fan sheave, a main belt idler sheave secured to one of said vertical members having means for vertical adjustment, said pump having a tube connection to said lower header. l

2. A device of the class described, comprising side base members, vertically positioned channels secured to the front end of said base members and having their flanges turned inwardly, a radiator core comprising upper and lower headers having tubes therebetween and a multiplicity of lns through which said tubes extend, one of said headers at its ends .being secured to said channels, 'the ends of the other header being slidably mounted on said channels, vertically positioned supplemental frame members secured to the rear end of said base members and extending vertically therefrom to a point midway said channels and secured thereto and having a connecting brace member between the upper ends thereof,

ymultiple V belt sheave secured to the rear end of the shaft of said fan, a cooling liquid circulating pump having a V belt sheave and a belt forming an operative connection to one of the grooves of said fan sheave, a main belt idler sheave secured Y to one o1' said vertical members having means for adapted to surround the exposed portion of thelblades of said fan.

' s. A avi u recited in claim 2 including, said .upper header having an inlet connection and an overowtank connected to the top thereof, said .tank having means whereby vapor :nay escape therefrom.
